看了 we find three central variants distinguished by amino acid changes, which we have named A, B, and C, with A being the ancestral type according to the bat outgroup coronavirus. The A and C types are found in significant proportions outside East Asia, that is, in Europeans and Americans. In contrast, the B type is the most common type in East Asia, and its ancestral genome appears not to have spread outside East Asia without first mutating into derived B types, pointing to founder effects or immunological or environmental resistance against this type outside Asia. 大概就是，有三种类型ABC，a是蝙蝠那来的原始病毒，bc是变种病毒。a和c是欧美品种，b是东亚品种。b没有突变在东亚以外的地区传播。 我觉得这个自媒体解读大致上没什么问题

你再仔细读一下原文吧，特别是这句:These American patients are reported to have had a history of residence in the presumed source of the outbreak in Wuhan. 还是保持清醒，别被自媒体带节奏了。

最好自己看看论文吧……至少看一下conclusion
你根本就没看文章，文章只是说了中国跟美国的病毒不是一个种类。研究人员发现在人类中最早出现的原始版本的新冠病毒“A型”，虽然出现在武汉，但并没有在武汉流行开来，而是在美国更为常见。而在武汉流行开来，其实是从原始版病毒变异而来的“B型”。
我不看就知道是假的，因为我坚信中国是发源地
不懂瞎猜。
说不得，待会有人要过来说你上班了。这街上屁股大于科学。
楼主标题是不合适，但是微博内容基本正确
你祖国今天晚上又要死两千了
是的a型作为初代，在所谓疫源地武汉没流行，欧洲没流行，美国澳大利亚流行了。论文的观点基调疫源还是武汉，但是比较搞笑
这两千人里面不会有你吧？
那你肯定就是二鬼子
…对，人家结论并没有说美国是源头
看了

这种个例不能算传出吧，这里的传出应该是大规模传染了。
他应该看不懂英文
笑死我了，“坚信”这种也叫科学？那不应该叫信仰么
我个人对发源地这种早就zz化的东西而产生的无谓争论毫无兴趣，不过那哥们说“我不看就知道是假的，因为我坚信中国是发源地”这种更加zz化的说法，岂不是更不科学、更加屁股决定脑袋。
看了下，论文第四段说了A型的基因亚群中，有四个中国人带有原始基因组，三名日本人和两名美国人具有许多突变，而美国患者推测在武汉有过居住史。所以这篇论文还是推测最早的起源在武汉。
你再仔细读一下原文吧，特别是这句:These American patients are reported to have had a history of residence in the presumed source of the outbreak in Wuhan. 还是保持清醒，别被自媒体带节奏了。
对啊，同样可以解读为武汉的病毒有可能是这些人带进来的啊。。
用坚信这话就不科学啊
所以这也是一种可能性，但是这些自媒体解读成a类病毒来源于居住于武汉的美国人，显然是具有误导性的，文章并没有指出病毒真正来源地。而且也有很多人质疑论文是水文了(样本量太少，推导结论不科学，论文作者之一是研究考古学的)，所以还是不要太当真。
别双标啊 学术不是这样搞的… 那也有可能不是啊。这样不就和美国佬差不多了
没双标啊，我只是说这个文章并没有更倾向于中国人是零号病人啊。而且从常识判断，美国人流行的病毒A比武汉流行的病毒B更接近野生病毒，难道不是美国人带进来武汉的可能性更大吗？
当然说这个文章本身观点对不对都存疑，但是如果他说的是对的，肯定我说的可能性更大啊
